a reaction vessel contains 13.9g of CO and 13.9g of O2. How many grams of CO2 could be produced according to the following reaction? 2CO + O2 ---> 2CO2
The question in the lab is asking what percentage by mass is the calcium, chloride and water in the orginal solution for each trial. In this lab we performed two trials, in each, we added 50 mL water to 2.0 g of CaCl2.
why is it not necessary to precisely measure the amount of water added to the sodium chloride in the procedure
